Blockchain is a decentralized ledger that records transactions across multiple computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This ensures transparency, security, and immutability in the transaction process.

3. How Cryptocurrency Works

Cryptocurrency operates through a peer-to-peer network, where participants can send and receive digital coins without the need for intermediaries. Users can purchase, sell, or trade cryptocurrencies using various online platforms, mobile applications, or exchanges.
